wise in cells, each adapted to receive a singlegrain. Another of itsobjects is to release the superfluous grainwhen two grains may chance to occupy the same cell, and another of its objects is to dislodge and arrange dis- I 5 arranged grains without'breaking-th'em. The object first named is attained by placing an oscillating feeder alongside thecells of the seed-plate, the second object is attained by leaving the cells open on one side and providing an open space into which the superfluousgrains may escape, and the third'object is attained by setting the cut-off in an oblique position, so thatthe yield ofthe e'ngaging'en'd of the cut-off will be upward and backward with relation to thedirection of the'travel ofthe cells.

The invention is exemplified in the structure hereinafter described, and it is definedin the appended claims.

In the drawings forming part of this specification, Figure 1 is a plan of the bottom ,of a seedbox constructed in accordance with my invention. Fig. 2 is an elevation of the seedbox-bottom. Fig. 3 is a plan of the hot tom plate and the feeder-plate of the seed box. Fig. 4 is a-section on line X in Fig. 1. Fig. 5 is an elevation of the feeder-plate.

At 1 is shown an annular plate to which the seedbox is attached, and at 2 is shown a disk concentric with the annular plate 1. The disk is smaller in its greatest diameter than the smallest diameter of plate 1, and between the plate and the disk is a groove that describes the greater part of a circle. The disk 2 and the plate 1 are cast in one piece. They constitute a cover for the seedwheel, and the circular slot in thecoverpcrinits the passage of corn to the exposed seedcells. A cut-off housing 6 is attached to the cover-disk by means of a bolt 7, and the shank 8 of the cut-off 8 has oblique sliding bearings in thehousing 6. The shank of the cutoff extends upward and backward in the housing, and it has a spring, as 9 in Fig 2, that tends to hold the cut-0E protruded and in contact with the seed-Wheel. The seed-Wheel L is in this instance anannular rim with gearteeth 4 projecting obliquely from its perimeter and seed-cells 5 cut into its inner surface.

The upper surfaceof the bottom plate 10 is flush with the uppersurface of'the seed-wheel. At the inner circle of the seed-Wheel the bottom plate jogs downward to form the inner wall of the seed-cells, and a flange 11 on the perimeterof the bottom plate forms a support for the seed-wheel and a bottom for the cells thereof. At a point in the cut-off housing the flange 11 is cut away, as shown at 11 in Fig. 3, to form a discharge-opening for the grain. The disk 2 of the cover-plate is smaller in diameter than the diameter of the circle of the seed-cells, and a part of the raised surface of the bottom plate-is exposed. At

one or more places the raised part of the bot-- tom plate is cut away from the cells, as shown hereinafter explained.

A feedei' plate 13 is pivoted between the cover-plate disk and the bottom plate. It conforms in outline for a part of its circumference to the disk2, and it has a pair of downward-extending fingers 14, that pass through a slot in the bottom plate and straddle an eccentric cam 23 on a drive-shaft 21. A part of the perimeter of the feeder-plate projects beyond the disk of the cover-plate, as shown at 15, and this extended part is raisedland pro vided with protuberances capable of agitating the corn. A part 19 of the feeder-plate may extend overthe seed-cells in the rear of the cut-off housing, and bearings 18 may exfingers 14. The feeding-surface 15 extends alongside the cells of the seed-wheel, and the agitation imparted to the seed by the oscillating motion of the feederinsures the filling of the seed-cells by grains on edge. If two grains should be carried by one cell, one will of necessity extend above the seed-wheel and engage the cut-off, and the cut-off will yield backward and upward, raising the point of contact with the grain until sufficient leverage is gained to tilt the extra grain out of the cell. As the feeder-plate oscillates the extension 19 passes in and out below the cutoff housing in the rear thereof and tends to force corn into the cells. Should it force two grains to occupy one cell, one lying alongside the other, the outer one will be forced over into, one of the cut-away spaces 12 by an incline 20, while the other, if disarranged in the cell, will be carried back into position by the inclined surface at the end of the cutaway space.

The protuberances on the'stirringsurface 15 of the feeder-plate may be made of any desired shape and size, and they may even be omitted without losing all the advantages derived from the oscillating motion. The protuberances are preferably rounded on their edges to avoid cutting the corn.

I. In a dropper for corn-planters, the combination with a seed-wheel having seed-receiving cells, of a stationary wall alongside one side of the line of travel of the cells, and an Oscillating wall along the opposite side of the line of travel of the cells.

2. In a dropper for corn-planters, the combination with a seed-wheel having seed-receiving cells, of a stationary wall alongside one side of the line of travel of the cells,'an oscillating wall along the opposite side of the plate through slots 17' line of travel of the cells, and extensions on the oscillating wall projecting toward the cells. a

3. In a dropper for corn-planters, the'combination of a seed-wheel having seed-receiving cells, a plateabove the seed-wheel having a feeder extension disposed alongside the lineof travel of the cells, a pivot for the feeder-plate concentric with the seed-wheel, means for rotating the seed-wheel and means for oscillating the feeder-plate.

i. In a dropper for corn-planters, the combination of a seed-wheel having seed-receiving cells, a feeder-plate pivoted concentric with the seed-wheel, fingers depending from the feeder-plate and "a cam between the fingers to impart oscillatingmotionto the feederplate.

5. Ina dropper for corn-planters, the combination of a toothed seed-wheel having seedreceiving cells, a feeder-plate pivoted concentric with the seed-wheel, fingers depending from the feeder-plate, a shaft below the seedwheel a pinion on the shaft to drive the seedwheel and a cam on the shaft to oscillate the feeder-plate by engaging the-fingers thereof.

the housing tending to hold the operative end of the cut-off,'protruded from the housing.

In testimony whereof I sign my name in the presence of two subscribing witnesses.
